LONDON (AP) — Part of a terminal at Heathrow Airport in London was evacuated Monday because of a possible hazardous material, authorities said.

A Heathrow spokesperson said the check-in area at Terminal 4 was closed and evacuated while emergency services responded.

Passengers could be seen outside the terminal as firefighters responded to the scene. The evacuation was a precaution, the London Fire Brigade said.

The airport asked passengers not to travel to the terminal. All other terminals were operating.
